Sesquiterpene Classification

Sesquiterpenes are a class of volatile organic compounds found in cannabis and other plants, characterized by 15-carbon molecular structures (three isoprene units). In cannabis breeding records, sesquiterpene-dominant profiles are often associated with earthy, woody, spicy, and herbal aromatics commonly tagged in strains like Haze and Skunk lineages. Breeders analyze sesquiterpene ratios alongside monoterpenes to predict aromatic phenotypes and stability across generations. Sesquiterpene levels typically develop later in flower maturation than lighter monoterpenes, making harvest timing a key variable in final aroma expression.

Breeders working in sesquiterpene-rich categories use gas chromatography and selective crosses to stabilize complex aromatic profiles sought in heritage and modern cultivars. Sesquiterpene abundance is often correlated with plant vigor and stress response, making it relevant to phenotype stability and environmental adaptation studies.
